05 Dodge Neon SXT/Mopar Kicker Sub?

I have an 05 Neon SXT and want to get the Mopar Kicker Sub (that%26#039;s form fit to the trunk panel). There%26#039;s one listed on EBAY that shows it as a %26quot;plug and play%26quot; device. I%26#039;ve looked and looked and cannot locate a plug in my trunk space. Is it totally hidden to the naked eye or does my car just not have one even though my Dodge dealer has said that this sub (with same part number) is the specified one for my car? HELP!? Anyone!! If you have pictures of the location or how yours plugs in, it would be greatly appreciated.
